+
+## Critical rules
+
+- *Never include `payment_method_types` in any Stripe API call*, with one exception: Terminal (in-person payments) integrations must pass `payment_method_types: ['card_present']` on the PaymentIntent. For all other integrations, omit this parameter entirely to enable dynamic payment methods, which enables you to configure payment method settings from the Dashboard and dynamically display the most relevant eligible payment methods to each customer to maximize conversion. To customize which payment methods you accept, use [`payment_method_configurations`](https://docs.stripe.com/payments/payment-method-configurations.md) or `excluded_payment_method_types` instead of `payment_method_types`.
+
+## Key documentation

+
+## When to use Billing APIs
+
+If the user has a recurring revenue model (subscriptions, usage-based billing, seat-based pricing), use the Billing APIs to [plan their integration](https://docs.stripe.com/billing/subscriptions/design-an-integration.md) instead of a direct PaymentIntent integration.
+
+Review the [Subscription Use Cases](https://docs.stripe.com/billing/subscriptions/use-cases.md) and [SaaS guide](https://docs.stripe.com/saas.md) to find the right pattern for the user’s pricing model.
+
+## Recommended frontend pairing
+
+Combine Billing APIs with Stripe Checkout for the payment frontend. Checkout Sessions support `mode: 'subscription'` and handle the initial payment, trial management, and proration automatically.
+
+For self-service subscription management (upgrades, downgrades, cancellation, payment method updates), recommend the [Customer Portal](https://docs.stripe.com/customer-management/integrate-customer-portal.md).
+
+## Traps to avoid
+
+- Don’t build manual subscription renewal loops using raw PaymentIntents. Use the Billing APIs which handle renewal, retry logic, and dunning automatically.
+- Don’t use the deprecated `plan` object. Use [Prices](https://docs.stripe.com/api/prices.md) instead.
+- Don’t skip tax setup. See [Collect taxes for recurring payments](https://docs.stripe.com/billing/taxes/collect-taxes.md).
+- *Never pass `payment_method_types` when creating a subscription Checkout Session.* Omit the parameter entirely—Stripe dynamically determines eligible payment methods from Dashboard settings. Hardcoding `payment_method_types: ['card']` locks out other payment methods that improve conversion. See [dynamic payment methods](https://docs.stripe.com/payments/payment-methods/dynamic-payment-methods.md). Correct pattern:
+
+```ts
+const session = await stripe.checkout.sessions.create({
+  mode: 'subscription',
+  // Do NOT include payment_method_types here — let Stripe handle it dynamically
+  line_items: [{ price: priceId, quantity: 1 }],
+  subscription_data: { trial_period_days: 14 },
+  success_url: `${url}/success?session_id={CHECKOUT_SESSION_ID}`,
+  cancel_url: `${url}/pricing`,
+});

+# Connect / platforms
+
+## Table of contents
+
+- Accounts v2 API
+- Controller properties
+- Charge types
+- Integration guides
+
+## Accounts v2 API
+
+For new Connect platforms, ALWAYS use the [Accounts v2 API](https://docs.stripe.com/connect/accounts-v2.md) (`POST /v2/core/accounts`). This is Stripe’s actively invested path and ensures long-term support.
+
+**Traps to avoid:** Don’t use the legacy `type` parameter (`type: 'express'`, `type: 'custom'`, `type: 'standard'`) in `POST /v1/accounts` for new platforms unless the user has explicitly requested v1.
+
+## Controller properties
+
+Configure connected accounts using `controller` properties instead of legacy account types:
+
+| Property                            | Controls                                     |
+| ----------------------------------- | -------------------------------------------- |
+| `controller.losses.payments`        | Who is liable for negative balances          |
+| `controller.fees.payer`             | Who pays Stripe fees                         |
+| `controller.stripe_dashboard.type`  | Dashboard access (`full`, `express`, `none`) |
+| `controller.requirement_collection` | Who collects onboarding requirements         |
+
+Use `defaults.responsibilities`, `dashboard`, and `configuration` as described in [connected account configuration](https://docs.stripe.com/connect/accounts-v2/connected-account-configuration.md).
+
+Always describe accounts in terms of their responsibility settings, dashboard access, and [capabilities](https://docs.stripe.com/connect/account-capabilities.md) to describe what connected accounts can do.
+
+**Traps to avoid:** Don’t use the terms “Standard”, “Express”, or “Custom” as account types. These are legacy categories that bundle together responsibility, dashboard, and requirement decisions into opaque labels. Controller properties give explicit control over each dimension.
+
+## Charge types
+
+Choose one charge type per integration — don’t mix them. For most platforms, start with destination charges:
+
+- **Destination charges** — Use when the platform accepts liability for negative balances. Funds route to the connected account via `transfer_data.destination`.
+- **Direct charges** — Use when the platform wants Stripe to take risk on the connected account. The charge is created on the connected account directly.
+
+Use `on_behalf_of` to control the merchant of record, but only after reading [how charges work in Connect](https://docs.stripe.com/connect/charges.md).
+
+**Traps to avoid:** Don’t use the Charges API for Connect fund flows — use PaymentIntents or Checkout Sessions with `transfer_data` or `on_behalf_of`. Don’t mix charge types within a single integration.
+
+## Integration guides
+
+- [SaaS platforms and marketplaces guide](https://docs.stripe.com/connect/saas-platforms-and-marketplaces.md) — Choosing the right integration shape.
+- [Interactive platform guide](https://docs.stripe.com/connect/interactive-platform-guide.md) — Step-by-step platform builder.

+# Payments
+
+## Table of contents
+
+- API hierarchy
+- Integration surfaces
+- Payment Element guidance
+- Saving payment methods
+- Dynamic payment methods
+- Deprecated APIs and migration paths
+- PCI compliance
+
+## API hierarchy
+
+Use the [Checkout Sessions API](https://docs.stripe.com/api/checkout/sessions.md) (`checkout.sessions.create`) for on-session payments. It supports one-time payments and subscriptions and handles taxes, discounts, shipping, and adaptive pricing automatically.
+
+Use the [PaymentIntents API](https://docs.stripe.com/payments/paymentintents/lifecycle.md) for off-session payments, or when the merchant needs to model checkout state independently and just create a charge.
+
+**Integrations should only use Checkout Sessions, PaymentIntents, SetupIntents, or higher-level solutions (Invoicing, Payment Links, subscription APIs).**
+
+## Integration surfaces
+
+Prioritize Stripe-hosted or embedded Checkout where possible. Use in this order of preference:
+
+1. **Payment Links** — No-code. Best for simple products.
+1. **Checkout** ([docs](https://docs.stripe.com/payments/checkout.md)) — Stripe-hosted or embedded form. Best for most web apps.
+1. **Payment Element** ([docs](https://docs.stripe.com/payments/payment-element.md)) — Embedded UI component for advanced customization.
+   - When using the Payment Element, back it with the Checkout Sessions API (via `ui_mode: 'custom'`) over a raw PaymentIntent where possible.
+
+**Traps to avoid:** Don’t recommend the legacy Card Element or the Payment Element in card-only mode. If the user asks for the Card Element, advise them to [migrate to the Payment Element](https://docs.stripe.com/payments/payment-element/migration.md).
+
+## Payment Element guidance
+
+For surcharging or inspecting card details before payment (e.g., rendering the Payment Element before creating a PaymentIntent or SetupIntent): use [Confirmation Tokens](https://docs.stripe.com/payments/finalize-payments-on-the-server.md). Don’t recommend `createPaymentMethod` or `createToken` from Stripe.js.
+
+## Saving payment methods
+
+Use the [Setup Intents API](https://docs.stripe.com/api/setup_intents.md) to save a payment method for later use.
+
+**Traps to avoid:** Don’t use the Sources API to save cards to customers. The Sources API is deprecated — Setup Intents is the correct approach.
+
+## Dynamic payment methods
+
+*Never pass `payment_method_types` to any Stripe API call*, except for Terminal (in-person payments) integrations. Omitting this parameter enables [dynamic payment methods](https://docs.stripe.com/payments/payment-methods/dynamic-payment-methods.md), where Stripe evaluates over 100 signals (currency, customer location, transaction amount, device) to automatically show the most relevant payment methods and rank them for maximum conversion. Payment methods are managed from the [Dashboard](https://dashboard.stripe.com/settings/payment_methods) with no code changes required.
+
+This applies to all integration patterns:
+
+- `checkout.sessions.create`: omit `payment_method_types` entirely. Dynamic method selection is the default behavior.
+- `paymentIntents.create`: omit `payment_method_types`. On API versions 2023-08-16+, dynamic methods are the default. On older versions, pass `automatic_payment_methods: { enabled: true }`.
+- `setupIntents.create`: same as PaymentIntents above.
+- `subscriptions.create`: omit `payment_settings.payment_method_types`. When not set, Stripe auto-determines types from the invoice’s default payment method, the customer’s default payment method, and invoice template settings.
+- **Terminal** (`paymentIntents.create`): pass `payment_method_types: ['card_present']`. Required for all in-person payments. In Canada, also include `interac_present`: `['card_present', 'interac_present']`. This is the only valid use of `payment_method_types`.
+
+See the [integration options guide](https://docs.stripe.com/payments/payment-methods/integration-options.md) for full details on dynamic versus manual configuration.
+
+**Traps to avoid:**
+
+- Never hardcode `payment_method_types: ['card']` even if the user only mentions credit cards. Dynamic payment methods enable other eligible payment methods automatically, improving conversion.
+- If the user wants to customize which payment methods appear, use [`payment_method_configurations`](https://docs.stripe.com/payments/payment-method-configurations.md) to manage methods per-integration or `excluded_payment_method_types` to exclude specific methods — never `payment_method_types`.
+- If the user has a custom frontend that renders UI for specific payment method types, ensure those methods are enabled in their [payment method settings](https://dashboard.stripe.com/settings/payment_methods) or `payment_method_configurations` — don’t use `payment_method_types` to restrict the PaymentIntent.
+
+## Deprecated APIs and migration paths
+
+Never recommend the Charges API. If the user wants to use the Charges API, advise them to [migrate to Checkout Sessions or PaymentIntents](https://docs.stripe.com/payments/payment-intents/migration/charges.md).
+
+Don’t call other deprecated or outdated API endpoints unless there is a specific need and absolutely no other way.
+
+| API          | Status     | Use instead                         | Migration guide                                                                          |
+| ------------ | ---------- | ----------------------------------- | ---------------------------------------------------------------------------------------- |

+| Tokens API   | Outdated   | Setup Intents or Checkout Sessions  | —                                                                                        |
+| Card Element | Legacy     | Payment Element                     | [Migration guide](https://docs.stripe.com/payments/payment-element/migration.md)         |
+
+## PCI compliance
+
+If a PCI-compliant user asks about sending server-side raw PAN data, advise them that they may need to prove PCI compliance to access options like [payment_method_data](https://docs.stripe.com/api/payment_intents/create.md#create_payment_intent-payment_method_data).
+
+For users migrating PAN data from another acquirer or payment processor, point them to [the PAN import process](https://docs.stripe.com/get-started/data-migrations/pan-import.md).

+- Restricted API keys (RAKs)
+- IP restrictions
+- Incident response
+- Webhook security
+- Mobile and client-side integrations
+- OAuth and CSRF protection
+- Two-factor authentication
+- Connect security
+- SAML and SCIM
+
+## API keys
+
+Never include keys in source code. You might find example code like `client = new Stripe("sk_...")` that are for illustration only. Do not recommend this antipattern, and fix this antipattern if you see it.
+
+Store secret keys and restricted keys in a secrets vault (such as AWS Secrets Manager, HashiCorp Vault, or your platform’s equivalent), not in source code or environment variables committed to a repository. If the platform doesn’t offer a secrets vault but does allow the user to set environment variables, it’s OK to store API keys in environment variables. Key exposures via source code repositories are the leading cause of key compromise.
+
+Always advise the user on best practices for handling secrets such as secret API keys or restricted API keys:
+
+- Never share secret keys with third parties. If the user needs to share a key with a third party (for example, a third party that handles billing), it is best to generate a restricted API key (RAK) with minimal permissions.
+- Rotate Stripe API keys when personnel with access to those keys depart.
+- Read [best practices for managing secret API keys](https://docs.stripe.com/keys-best-practices.md).
+
+Code must never log keys or include them in error messages or analytics. Remove those from logs if you find them.
+
+Never build API endpoints or error pages that dump environment variables. In addition to Stripe API keys, the environment may have other secrets.
+
+Use separate keys for separate environments (production, staging, QA). This limits the blast radius if any single key is compromised.
+
+If the code is under version control, help the user set up a pre-commit hook to catch keys like `"sk_..."` and `"rk_..."` in source code.
+
+**Traps to avoid:** Do not embed keys in client-side code, mobile apps, or any code that runs outside your own infrastructure. Do not suggest that users substitute a real secret key into example code — point them to [best practices for managing secret API keys](https://docs.stripe.com/keys-best-practices.md) instead.
+
+## Restricted API keys (RAKs)
+
+Use [restricted API keys](https://docs.stripe.com/keys/restricted-api-keys.md) (prefix `rk_`) instead of secret keys (prefix `sk_`) wherever possible. RAKs have only the permissions you assign, so a compromised RAK can do far less damage than a compromised secret key.
+
+Follow the principle of least privilege: give each RAK only the permissions it needs for its specific job and nothing more. Create a separate RAK for each service or use case.
+
+Preferred migration approach:
+
+1. Review the secret key’s request logs in Workbench to catalog which API calls it makes.
+1. Create a RAK in test mode with matching permissions.
+1. Use the [Stripe CLI](https://docs.stripe.com/stripe-cli.md)’s `stripe logs tail` command to watch logs.
+1. Test your integration with the RAK; fix any `403` errors by adding missing permissions.
+1. Create the equivalent live-mode RAK and replace the secret key.
+1. Rotate or expire the old secret key once confident.
+
+**Traps to avoid:** Do not default to recommending secret keys. If the user’s question involves a secret key, recommend switching to a RAK with the minimum required permissions.
+
+## IP restrictions
+
+Encourage users to add an [IP allowlist](https://docs.stripe.com/keys.md#limit-api-secret-keys-ip-address) to every API key. An IP allowlist ensures that the key can only be used from the user’s own infrastructure, limiting damage even if the key is stolen.
+
+Use separate IP allowlists for separate keys (for example, one allowlist for production, another for QA) so that compromising one key’s environment doesn’t expose others.
+
+## Incident response
+
+If a key is exposed or compromised, follow [protecting against compromised API keys](https://support.stripe.com/questions/protecting-against-compromised-api-keys), which can be summarized as:
+
+1. **Roll the key immediately** — go to the [API keys page](https://dashboard.stripe.com/apikeys) and roll or delete the exposed key. Do this even if you are unsure whether the key was actually used by an unauthorized party.
+1. **Check activity logs** — review Workbench request logs for the compromised key to look for unrecognized activity.
+1. **Contact Stripe support** if you see activity you don’t recognize.
+
+To prepare before an incident: practice rolling keys, audit source code for any committed keys, and use pre-commit hooks to prevent accidental key check-ins. See [protecting against compromised API keys](https://support.stripe.com/questions/protecting-against-compromised-api-keys).
+
+## Webhook security
+
+Always [verify webhook signatures](https://docs.stripe.com/webhooks.md#verify-events) using Stripe’s webhook signing secret. Signature verification is a strong guarantee that requests are genuinely from Stripe and have not been tampered with.
+
+For defense in depth, also [allowlist Stripe’s IP addresses](https://docs.stripe.com/ips.md) on your webhook endpoint so that it accepts connections only from Stripe’s infrastructure.
+
+**Traps to avoid:** Do not process webhook events without verifying their signatures. Unverified webhooks can be spoofed.
+
+## Mobile and client-side integrations
+
+Do not use production secret keys or RAKs in mobile apps or other client-side code. Client-side code can be extracted and keys decompiled.
+
+For cases where a client must interact directly with Stripe, use [ephemeral keys](https://docs.stripe.com/issuing/elements.md#ephemeral-key-authentication). Ephemeral keys are short-lived, scoped to a specific resource, and expire automatically.
+
+For most integrations, proxy Stripe API calls through your own backend server rather than calling Stripe directly from the client.
+
+## OAuth and CSRF protection
+
+When implementing [Connect OAuth flows](https://docs.stripe.com/connect/oauth-reference.md), always use the `state` parameter to protect against CSRF attacks. Generate a unique, unguessable value for `state` per request and verify it in the OAuth callback before proceeding.
+
+This applies to all Stripe OAuth surfaces: Connect, Link, and Stripe Apps.
+
+## Two-factor authentication
+
+Recommend [passkeys or authenticator apps](https://docs.stripe.com/security.md) rather than SMS-based 2FA for Stripe Dashboard access. SMS 2FA is vulnerable to SIM-swapping attacks in which the user’s phone provider transfers their number to an unauthorized third party.
+
+Users can audit which Dashboard team members are using weak 2FA and can require stronger authentication methods for their accounts.
+
+## Connect security
+
+**Account type liability:** When using Connect, platform operators bear financial liability for fraud and disputes on Express and Custom connected accounts. Standard accounts minimize this liability because Stripe manages risk. Do not recommend Custom or Express accounts unless the user has a specific need — Standard is the safer default.
+
+**Connect onboarding:** Use [Stripe-hosted onboarding](https://docs.stripe.com/connect/onboarding.md) rather than building a custom onboarding flow. Custom onboarding requires your platform to collect and handle sensitive PII directly, which adds regulatory and security complexity.
+
+## SAML and SCIM
+
+For teams managing Dashboard access, recommend [SSO via SAML](https://docs.stripe.com/get-started/account/sso.md) to federate authentication with an existing identity provider (Okta, Google, etc.). SSO centralizes access control and simplifies offboarding.
+
+[SCIM provisioning](https://docs.stripe.com/get-started/account/sso/scim.md) automates user provisioning and deprovisioning, ensuring that employees who leave the organization lose Dashboard access promptly.

+
+## Table of contents
+
+- When tax applies
+- Two-step setup
+- If jurisdictions are unknown
+- If the region or tax type isn’t supported
+
+## When tax applies
+
+Use Stripe Tax for any subscription, invoice, or Checkout Session where the merchant has customers across multiple jurisdictions. It handles sales tax, VAT, and GST automatically based on the customer’s location and the merchant’s active registrations. See the [Tax overview](https://docs.stripe.com/tax.md) for supported regions and tax types.
+
+## Two-step setup
+
+1. Add a registration for each jurisdiction where the merchant is obligated to collect tax. Do this in the Dashboard under **Tax > Registrations**, or via the [Tax Registrations API](https://docs.stripe.com/api/tax/registrations.md).
+1. Pass `automatic_tax: { enabled: true }` on the [Subscription](https://docs.stripe.com/api/subscriptions.md), [Invoice](https://docs.stripe.com/api/invoices.md), or [Checkout Session](https://docs.stripe.com/api/checkout/sessions.md) object.
+
+It’s safe to enable `automatic_tax` before any registrations exist — Stripe won’t collect tax until at least one registration is active.
+
+**Traps to avoid:** `automatic_tax` and explicit `tax_rates` are mutually exclusive. For existing subscriptions, clear `default_tax_rates` and all item-level `tax_rates` before enabling `automatic_tax` — the update will fail otherwise. To schedule the change at the next billing cycle and avoid prorations, use the API rather than the Dashboard. For bulk migrations, use the [Tax migration tool](https://docs.stripe.com/billing/taxes/migration.md).
+
+**Traps to avoid:** For EU merchants, one OSS union registration covers all 27 member states. Don’t register an individual EU country separately unless the merchant has a physical presence there.
+
+## If jurisdictions are unknown
+
+Don’t guess which jurisdictions apply. Prompt the user: “Go to Dashboard > Tax > Registrations, add the states or countries where you have customers, then come back.”
+
+## If the region or tax type isn’t supported
+
+Check the [supported countries list](https://docs.stripe.com/tax/supported-countries.md). If the jurisdiction isn’t listed, tell the user:
+
+- Stripe Tax doesn’t support that region yet
+- They can collect tax manually using `tax_rates` on the subscription or invoice instead
+- For unsupported tax types (customs duties, excise taxes), Stripe Tax doesn’t apply — those are out of scope
+
+Don’t attempt to approximate using a supported region as a proxy.

+# Kordant
+
+**Multi-layered consumer identity protection against predatory AI-driven scams.**
+
+Kordant combines five service domains — voice cloning detection, dark web monitoring, spam classification, property monitoring, and data broker removal — into a unified platform with web, iOS, and Android apps.
+
+---
+
+## The Pitch
+
+Scammers are weaponizing AI at scale: voice clones that sound exactly like your family, hyper-personalized phishing messages that bypass filters, and synthetic identities that exploit stolen data within hours of a breach. Legacy credit monitoring is reactive — it tells you after the damage is done.
+
+Kordant flips the model. We detect the scam _as it happens_:
+
+- **VoicePrint** analyzes inbound calls in real time to flag synthetic AI-generated voices before you're socially engineered.
+- **DarkWatch** continuously monitors dark web forums, breach databases, and data broker caches — notifying you the moment your credentials, phone, or SSN surface.
+- **SpamShield** intercepts and classifies spam calls and SMS at the network level, blocking threats before they reach your phone.
+- **HomeTitle** monitors county deed records for unauthorized ownership changes, liens, and fraud.
+- **RemoveBrokers** automates data broker opt-out requests to remove your personal info from people-search sites.
+
+---
+
+## Architecture
+
+Unified SolidStart monolith with tRPC, Drizzle ORM, and native mobile apps.

+## Tech Stack
+
+| Layer | Technology |
+|-------|-----------|
+| **Language** | TypeScript (Node.js ≥22) |
+| **Framework** | SolidStart (SSR + API server) |
+| **API** | tRPC (type-safe RPC) |
+| **Database** | Turso / SQLite (Drizzle ORM) |
+| **Cache / Queue** | Redis 7 |
+| **Styling** | Tailwind CSS + CSS custom properties |
+| **Mobile iOS** | SwiftUI (native) |
+| **Mobile Android** | Jetpack Compose (native) |
+| **Extension** | Chrome Manifest V3 |
+| **Auth** | JWT + session cookies |
+| **Billing** | Stripe |
+| **Email** | Resend |
+| **Push** | Firebase Cloud Messaging + APNs |
+| **SMS** | Twilio |
+| **Design Tokens** | JSON → generated TS/Swift/XML |
+| **CI/CD** | Vercel (web) + Docker (scheduler) |
+| **Monorepo** | pnpm workspaces |
+| **Testing** | Vitest |
+
+---
+
+## Getting Started
+
+### Prerequisites
+
+- Node.js >= 22.0.0
+- pnpm >= 9.0.0
+
+### Setup
+
+```bash
+# Install dependencies
+pnpm install
+
+# Copy environment variables
+cp .env.example .env
+
+# Edit .env with your Turso credentials
+# DATABASE_URL=libsql://your-db.turso.io
+# DATABASE_AUTH_TOKEN=your-token
+
+# Run database migrations
+pnpm db:migrate
+
+# Start development server
+pnpm dev
+```
+
+The web app runs at `http://localhost:3000`.
+
+---
+
+## Design Tokens
+
+All platforms (web, iOS, Android) share the same design tokens defined in `design-tokens/`:
+
+```
+design-tokens/
+├── colors.json       # Brand, semantic, background, text, border colors
+├── typography.json   # Font family, scale, weights
+├── spacing.json      # 4px-based spacing scale
+├── shadows.json      # Elevation definitions
+└── radius.json       # Border radius scale
+```
+
+Generate platform-specific code:
+
+```bash
+node scripts/generate-tokens.mjs
+```
+
+This produces:
+- `web/src/theme/tokens.ts` — TypeScript constants
+- `iOS/Kordant/Theme/GeneratedTokens.swift` — SwiftUI colors + spacing
+- `android/.../res/values/generated_tokens.xml` — Android resources
+
+See `docs/BRAND_GUIDELINES.md` for full brand guidelines.
+
+---
+
+## Deployment
+
+| Component | Platform | Notes |
+|-----------|----------|-------|
+| Web app | Vercel | git push auto-deploys |
+| Database | Turso (managed) | run `pnpm db:migrate` to apply schema changes |
+| Background jobs | Docker on `pan` | scheduler + Redis containers |
+
+### Setting up the Scheduler (pan server)
+
+The background job scheduler (dark web scans, reports, etc.) runs as Docker containers on your `pan` server. Run the setup script from anywhere:
+
+```bash
+# From dev machine (SSHs into pan):
+bash scripts/setup-pan.sh
+
+# Or directly on pan:
+sudo bash scripts/setup-pan.sh
+```
+
+This installs Docker + Compose, clones the repo to `/opt/kordant`, creates a systemd service, and starts the scheduler. See the script for details and the optional Gitea post-receive hook for auto-deploy on push.
+
+### Scripts
+
+| Command | Description |
+|---------|-------------|
+| `pnpm dev` | Start web dev server |
+| `pnpm build` | Build web app for production |
+| `pnpm test` | Run web tests |
+| `pnpm lint` | Lint web app |
+| `pnpm db:migrate` | Run database migrations |
+| `pnpm db:seed` | Seed database with test data |
+| `pnpm build:ext` | Build browser extension |
+| `node scripts/generate-tokens.mjs` | Generate platform design tokens |
+| `bash scripts/setup-pan.sh` | Deploy scheduler to pan server |
+

+/**
+ * Application class for Kordant.
+ *
+ * ## Startup Optimization Strategy
+ *
+ * Initialization is split into three tiers to minimize time-to-interactive:
+ *
+ * **Tier 1 — Critical (main thread, blocks first frame)**
+ * Everything needed to determine auth state and show the initial UI.
+ * - [SecureStorageManager] (encrypted prefs for auth tokens)
+ * - [UserPreferencesDataStore] (user preferences)
+ * - [AuthRepository] (checks if user is logged in)
+ * - [StartupTracker] (measures startup timing)
+ * - [StrictModeConfig] (debug only — catches main-thread violations)
+ *
+ * **Tier 2 — Deferred (background thread, starts before first frame)**
+ * Heavy init that isn't needed for the first frame but should be ready
+ * shortly after the UI appears.
+ * - [SecurityChecker] (root detection — I/O heavy)
+ * - [NetworkModule] base URL config
+ * - [DatabaseModule] cache TTLs
+ *
+ * **Tier 3 — Lazy / Post-Frame (init on demand)**
+ * Everything that can wait until the user actually needs it.
+ * - Notification channels
+ * - WorkManager periodic sync
+ * - Crashlytics
+ * - App shortcuts
+ * - Widget updates
+ *
+ * This approach keeps Application.onCreate() under ~50ms on most devices,
+ * well within the 1.5s cold-start budget.

+ * Sensitive keys (encrypted on disk):
+ * - "current_user" — contains name, email, phone (PII)
+ * - "subscription" — may contain payment-related info
+ * - "voice_enrollments" — contains biometric voice prints
+ *
+ * Non-sensitive keys (plain JSON):
+ * - "users" — generic user data without direct PII
+ * - "watchlist" — monitoring targets (external entities)

+ * - "properties" — monitored property addresses
+ * - "spam_rules" — spam call rules
+ * - "voice_analyses" — analysis results (not raw prints)

+ * Token refresh on 401 is handled by [TokenRefreshAuthenticator] (an OkHttp [Authenticator]),

+ *
+ * ## Why Interceptor + Authenticator?
+ *
+ * - **Interceptor**: Runs on every request, BEFORE the response is examined.
+ *   We use it here to simply add the `Authorization: Bearer <token>` header.
+ * - **Authenticator**: Runs ONLY when the server responds with 401.
+ *   This is where we refresh the token and retry. Separating concerns
+ *   makes the code cleaner and avoids mixing request modification with
+ *   response handling in a single interceptor.

+/**
+ * Manages silent token refresh with rotation.
+ *
+ * ## Responsibilities
+ *
+ * - **Automatic refresh before expiry** — Parses JWT `exp` claim and refreshes
+ *   5 minutes before expiry ([REFRESH_GRACE_PERIOD_MS]).
+ * - **Token rotation** — Stores the new refresh token if the backend rotates it.
+ * - **Concurrent deduplication** — Only one refresh runs at a time.
+ * - **Exponential backoff** — On transient failures, retries with jitter.
+ * - **Permanent failure** — After 3 failed attempts, clears auth state so the
+ *   UI layer can show the login screen.
+ *
+ * ## Usage
+ *
+ * ```kotlin
+ * // Start periodic refresh on app startup
+ * tokenRefreshManager.startPeriodicRefresh()
+ *
+ * // Proactive refresh when app comes to foreground
+ * tokenRefreshManager.refreshIfNeeded()
+ * ```
+ *
+ * ## Thread Safety
